Points saillants

The first hit of sunshine could trigger storm slabs and loose snow avalanches from steeper, alpine features.

Problèmes avalancheux

  • Cornices

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    1–2
    Large cornices have formed and they remain fragile. Cornices are unpredictable and demand respect. Give them a wide berth from above and below.

  • Storm Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    1–2
    New storm slabs may have a poor bond to the underlying crust and be reactive at upper alpine elevations. Loose dry avalanches are possible from steep terrain features.

Confidence

Moderate - Due to the number and quality of field observations

Avalanche Summary

No new avalanche reports on Thursday.

Snowpack Summary

Rain over the past few days has saturated snow surfaces and only higher alpine elevations were lucky enough to get snow. With a forecast cooling trend, the upper snowpack will likely lock up as a firm crust. The average snowpack depth at treeline is 300 cm of well settled snow with no significant layers of concern.
